Diameter of circle = 1.4m
Radius of circle = 0.7m
Area of circle = π r sq.
22/7*0.7*0.7 = 1.54 m sq.
circumference of circle = 2πr
2*22/7*0.7 = 4.4 m

Hope it may help you

D=2r=1.4m

r=1.4/2

=0.7m

Circumference of metal sheet=2πr

=2×22/7×0.7

=44×0.1

=4.4m

Area of circle=πr²=22/7×4.9

=22×0.7=15.4m²
